Thanks for the feedback everyone!  Much appreciated.  I've been searching
for a 36GB SCA drive online and it's pretty hard to find a good candidate
for a new drive.  It looks like the industry is filled with misleading terms
like 'new pull' 'new bulk' and others that are all just used drives that
have been tested (or not).  While I would like to find 4-8 brand new drives
for my SS20's and SS10's, it looks like the cost is $100 - $200 for an
entirely new drive.  If anyone has any suggestions or _trustworthy_ sources
for a good drive, I'd appreciate if you could mail me privately..  thanks
everyone.  I'm almost wondering if I should just plug the old drives back in
and use them.. they are just so loud and hot.
